Chapter 4 Wiring CFP2000 4-1 System Wiring Diagram Figure 4-1 T Table 4-1 NOTE Please refer to Section 4-2 Wiring Diagram for detailed wiring information. 4-3 Power input terminal Please refer to Section 9 Specification Table in user manual for detail. NFB or fuse There may be a large inrush current during power on. Refer to 7-2 NFB to select a suitable NFB or 7-3 Fuse Specification Chart. Electromagnetic contactor Switching the power ON/OFF before the magnetic contactor more than 1 x per hour can cause damage to the drive.
AC reactor (input terminal) When the mains power capacity is > 500 kVA or when the drive is preceded by a capacitor bank, the instantaneous peaks voltages and current may destroy the drive. In that case it is recommended to install an AC input reactor which will also improve the power factor and harmonics. The cable between reactor and drive should be Zero-phase reactor environments with audio devices, and reduce input and output side interference. The effective range is AM band to 10 MHz. Please refer to Section 7-5. EMC filter Can be used to reduce electromagnetic interference. Please refer to Section 7-6.
Brake module & Brake resistor (BR) Used to shorten the deceleration time of the motor. Please refer to Section 7-1. AC reactor (output terminal) The wiring length of the motor will affect switching current peaks. It is recommended to install an AC output reactor when the motor wiring length exceeds the value listed in Section 7-4.
